CALK-PLATE FOR SHOES.

SPECIFICATION forming part of Letters Patent No. 394,863, dated December 18, 1888.

Application filed June 23, 1888. Serial No. 278,004. (No model.)

To aZZ whom it nmg concern:

Be it known that we, CHARLES KELLER- MANN and HENRY M. SoLvEsoN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Calk-Plates for Shoes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference bein had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Our invention relates particularly to detachable calk-plates for shoes, the fastening of the plate being effected by clamping it to the sole of the shoe. The plate is designed to be used by baseball players, by persons running, walking on ice, or climbing hills and mountains. For base-ball playing it is specially suited to the needs of amateur players. Such players do not care to trouble themselves to carry with them the professional shoes having permanently calked soles. If the professional shoes are used, they cannot be worn until the ball-grounds are reached. Consequently the player must wear walkingshoes to the grounds and carry the playingshoes.

Our detachable plates maybe carried in the pocket until the grounds are reached, and then attached to the ordinary walking-shoe. For walkingon ice or climbing hills the plates may be carried in the same way until needed.

In the accompanying drawings, Figure l is a perspective view of our improved plate. Fig. is a bottom of the plate expanded. Fig. 3 is a similar view of the plate clamped to a shoe.

The plate is composed of the two overlap ping sections A and B. The outer-portion of the section A is divided into the two arms A A each of which is turned upwardly and inwardly at the outer end to engage the sole of the shoe. The outer end of the section B is divided into the two arms 13 13*, which are also turned upwardly and inwardly to engage the opposite side of the sole of the shoe.

The section A has at its inner end a slot, A extending at right angles to the foot, and

said lever.

a headed post, 13*, extends through the said slot into the section B, and the section B has at its inner end a similar slot, B and a headed post, A, extends through said slot into said section A. This construction allows the sections A and B to slide upon each other at right angles to the foot, whereby the space between the upturned ends of the arms of said sections is increased and diminished. The slots A and B or one of them, should be wider than the thickness of the post passing through it, in order that the sections may turn a little upon each other. By this means the sections can adjust themselves to bring the ends of each of the arms against the edge of the sole of the shoe.

C is a cam-lever applied to the bottom of the sectionsA and B to draw the latter together, thus effecting the clamping of the calkplates to the shoe. At one end said lever loosely surrounds the post A, which latter is lengthened the thickness of said lever,.and said lever having a hole, 0, to receive said post. Near its middle said lever has an eccentric slot, C, which is occupied by the post B the latter being extended the thickness of The opposite end of said lever forms a handle by which to draw it. hen the plate is to be clamped to the shoe, the lever C is thrown forward until the post B stands in the end of the slot C farthest from the post A. The sections are then farthest apart. The plate is now laid against the sole of the shoe and the lever C drawn back. The wall of the eccentric slot C draws on the post B, and thereby draws the section B toward the section A until the plate is tightly clamped to the shoe. The outer wall of the slot C should be provided with one or more recesses c, in which the post B may lodge when the plate has been clamped sufficiently tight.

From the arm A depends a calk, A and from the arm B depends a calk, These calks may be riveted to said arms, or they may be a tongue out out of the arm and bent downwardly, as shown in the drawings. The arms A and B maybe provided with similar calks; but we prefer to extend one of the sections of the plate forward at the middle of the plate and bend it dowmwardly to form a calk, D.

The hole a in the lever C may be an elongated 0r semicircular slot, of such form as to receive the post A" in a recess at either end. This provides for more adjustment than is provided for by the eccentric slot 0. For a narrow foot the post A is set in the end of the slot 0 nearest the slot C, and for-a-wide foot said post is set in the other end of said slot c.

'0 claim as our invention- 1. Ina ca lk-plate, the combination of the calk-bearing sections A and 13, posts A" and I3", and the cam-lever (I, substantially as and for the purposes set forth.

2. In a calk-plate, the combimltion of the milk-bearing sections A and B, the canrlever 0, having the eccentric slot C, provided with one or more recesses, c, and posts A 13, substanlially as and for the pnr 'roses set forl h.

In testinionv whereof \ve allix our si 'natnres in presence ol two witnesses.
